CC -!- FUNCTION: Bifunctional enzyme which can phosphorylate or
CC dephosphorylate isocitrate dehydrogenase (IDH) on a specific serine
CC residue. This is a regulatory mechanism which enables bacteria to
CC bypass the Krebs cycle via the glyoxylate shunt in response to the
CC source of carbon. When bacteria are grown on glucose, IDH is fully
CC active and unphosphorylated, but when grown on acetate or ethanol, the
CC activity of IDH declines drastically concomitant with its
CC phosphorylation. {ECO:0000255|HAMAP-Rule:MF_00747}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[isocitrate dehydrogenase] = ADP + H(+) + O-
CC phospho-L-seryl-[isocitrate dehydrogenase]; Xref=Rhea:RHEA:43540,

CC ChEBI:CHEBI:456216; EC=2.7.11.5; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00747};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00747}.
CC -!- SIMILARITY: Belongs to the AceK family. {ECO:0000255|HAMAP-
CC Rule:MF_00747}.
